6700SR Refrigerated Sampler
51
Since the sampler may encounter more than one error during a pro-
gram, it does not display the messages continuously. Instead, it
records each error and the time it occurred in the Sampling Results
and Combined Results report. It alerts you to the recorded errors by
displaying the message, “ERRORS HAVE OCCURRED DURING
PROGRAM.” (See
Table 9 for a description of the errors and events.)
Fatal Error
Screen k will only show up if you are using a multiple bottle config-
uration and the distributor system fails. Failing the test can indi-
cate any of the following conditions:
• The distributor arm is not attached to the sampler.
• The stop arm on the distributor shaft extension is missing or
broken.
• The stop inside the refrigerator is missing or broken.
• The distributor drive mechanism inside the controller is mal-
functioning.
Warning Messages
Occasionally, the sampler displays a warning message to alert you
to a potential problem. There are two warnings. The first warning,
“REPLACE PUMP TUBE,” reminds you to check the condition of
the pump tube. For more information, see Replacing the Pump
Tube on page 70. The second warning reminds you that the inter-
nal battery is near expiration and should be replaced. You can find
instructions for replacing the battery in Replacing the Internal
Battery on page 75.
Interrupting a Running Program
You can interrupt a sampling program by pressing the Stop key
while the sampler is waiting for the next sample event. Pressing
Stop places the sampler into Manual Paused operation and records
a “MANUAL PAUSE” in the sample event log.
In this state, the sampler allows you to access several functions.
You can modify the program, take a grab sample, etc., with out ad-
versely affecting the running program. Modifying the program is
limited to adjusting the pacing intervals, enable conditions, sample
volume, and suction head. The basic program structure, such as the
type of pacing, can not be changed.
While in the manual paused state, the sampling program continues
to operate as normal, with the exception of taking samples. If a
sample was to be taken, it is skipped. The sampler records “SAM-
PLE SKIPPED” in the sample event log and continues to operate
as normal.
The manual paused state displays a scrolling menu with up to
twelve options. Use the Arrow keys to scroll through the manual
paused options and the Enter key to make a selection. Return to
the running program by selecting “RESUME PROGRAM” or press-
ing the
Stop key. If you do not make a selection, the sampler auto-
matically resumes the original sampling program five minutes
after the last key was pressed.
Warning Messages
Program Done Messages
At the completion of a multi-bottle
sampling program, the controller
“parks” the distributor towards
the back of the refrigerator. The
parked position allows for easier
access to the bottle rack.
